UNITED STATES moan PATENT DFFiCE 2 Claims.

My invention relates to improvements in pumping mechanisms, and refersparticularly to a pumping mechanism adapted for deep water welloperations.

5 The present invention covers improvements upon the invention shown,described and claimed in the application for patent filed by me onOctober 28, 1935, Serial No. 47,194.

The aim or purpose of this invention is to insure a more useful,practical and efficient pumping mechanism with the same general objectsin view disclosed in said application.

One of the main objects of my invention is the provision of a lateraladjustment mechanism which will allow the adjustment of the impellershaft, while said shaft is in motion, to raise or lower the impellerswith reference to the seat for such impellers to allow dirt, sand,gravel or other foreign matter to be discharged before the flow of purewater and thus prevent injury to the impellers and contiguous parts ofthe pump mechanism.

Another object of my invention is the provision of a lateral adjustmentmechanism having means for raising and lowering the shaft carrying theimpellers without stopping the pump or interference with the generaloperation of the pump while pump is operating, thus saving a greatamount of time, labor and money usually caused by this operation.

Another object of my invention is the provision of a pumping mechanismwhich by reason of its ease of adjustment of the impeller shaft while itis in motion will save much wear and tear upon the impellers andassociated parts and thereby impart durability and long life "to theworking parts of the pump mechanism. Another object of my invention isthe provision of a pumping mechanism of the character stated 40which'will provide efllcient lubrication or all working parts under allconditions and which mechanism in every respect will prove practical,

desirable and emcient.

Another object of my invention is the provision of 'a full floatinglateral adjusting mechanism of character stated which will provideeiilcient cooling of the thrust bearing carrying the pump shaftonaccount of said thrust bearing being above the heat of the electricmotor and which provides more air space around thrust bearing.

Another object of my invention is the provision of a full floatinglateral adjusting mechanism,

that will indicate the amount of wear on the imnism stated.

for the face of the impeller thereby preventing water from by-Passing orshort-circuiting be- I tween the face of the impellers and their seats.10

Another object of my invention is the provision of a lateral adjustingmechanism which contains the main thrust bearing of the pump or impellerJ shaft independent of the electric motor which relieves all hydraulicthrust and shaft weight of! 16 themctor, thereby making the motor moreeflicient and giving longer life to both motor and pump thrust bearings.The pump shaft thrust bearing in my invention could fail and no damagewould be done to the motorv due to said bearing so being independent ofthe motor.

With these objects in view my invention consists of a full floatinglateral adjusting mechanism of the character and for the purposes statedembodying novel features of construction and as combination of parts,substantially'as described and claimed and as shown in the accompanyingdrawings, in which:

l5 being formed with an oil chamber l6 and being further provided with aseating or guiding portion l'l.

It will thus be noted that the housing or casing I of my pumpingmechanism comprises the lower or base section, the intermediate or rotorsection, and thetop section, and upon said top section is mounted thedome I8 through the medium of the hingeflil at one side, while oppositesaidv hinge connection the dome is retainedin closed H position by meansof the rod 20, and pin 2|,

passing through slot 22, said slot permitting the use ofa pin, or aflatkey or wedge as, found most From this construction it will b noted thatthe dome surmounts the top section and is normally held in lockedposition by means of the rod 20 and the pin 2|, but may be readilyraised or lowered when required by releasing pin 20, and with- I: ldrawing pin 2|, which allows the cover to bev i opened or closed on itshinge 19.

Mounted in the cylinder, seat or guide portion ll is the inverted shellor cartridge-23 having on its outer upper edge screw threads 24 withwhich engage the screw threads 25 on the inner face of slots 21 in whichfit thepins 28, andvupon its outer partingpartial'rotation to said ringand causing the pointer 32.

Fromthis construction it will be noted that the shell or cartridge ismounted for vertical movement inthe guide in the upper portion of mentof said shell or cartridge. 1

Passing entirely through the housing or casing is the rotary shaft 33which has the upper threaded end 34 receiving anut 35-and locked inposition for set adjustment by means of the key 36 and this nut restsupon the head or block 31, which rotor '40, and upon said shaft issecured the upper flange plate 4| carrying pins 42 which slide inopenings 43 of the hub 44, of the fan 45.

It will be noted that plate 44 is keyed to sleeve 39, and transmitspower therefrom to shaft 33, through pins 42, and plate 4|.

The fan 45 is thus located above the motor provided with the regulationvalve 56 and to which leads the water cooling pipe 51 while the oil tankor feedelement 58 ismountedin proper relation" to feed the'oil throughthe valve mechanismto thoil feed pipes53 and 54.

I V The lubricating system of my pumping mechanism is of paramountimportance as it insures :the lubricant being supplied in the properquantity, the supply governed or regulated and the temperature of thelubricant being of the proper fluid condition'in all kinds of weather.

From; this construction it will be evident that the oil is properly fedto the ball bearings atthe upper end of the-rotary shaft, intermediateand contiguous to the fan and rotor. and to the lower portion of saidshaft, which shaft passes. down through the bearing 59 throughout theentire length of the supply pipe. and at its lower end carries theduplicate or twin'impellers B0. and 60', as most, clearlyshown:-:inFig..2.

Dumping mechanism will be 1 readily v understood rapid rotation toth'eshaft which carries theim pellers and that such impellers arecapable of .being set and fixed initially in proper relation to thevalve seats in the inlet memberor nozzle, and that such impellers byraising of the supporting shell or cartridge-will permit the dis.-,

charge of any foreign matter preceding the flow of clear water, and thatthe vertical adjustment can be. made to-any degree to take up wear uponthe faces of the impellers to bring such faces in proper relation tothefacespf the seat rings to obtain the ,most efficient results.

It will be apparent that the placing of the fzm in the desired relationto the rotor will insure a draft of cool air to the rotor and otherenclosed mechanism to keep the moving parts of said mechanism in aproper cooled condition.

It will also-be noted that my lubricating system ensures the supply of aproper amount of lubricant to the moving parts of my mechanism and thatsuch lubricant under all conditions of weather will be supplied attliedesired tempera.- ture toinsure the most eificient results.

The many advantages of my pumping mecha- 'nism will be readilyunderstood and appreciated by all skilled and acquainted with such mechanection withthe drawings, the 0 eration'of m 3 edge said ring is formedwith teeth 29 withrwhicht p y engage the worm 30 having a keyed, stud 3|for I the application of a suitable implement for im-' nlsm and'furthercomment is deemed unneces- The novel'and most important feature of mypumping mechanism resides in the mechanism for adjusting the line shaftto set the impellers at the exact place desired in the bowls or cases,and the adjustment is efiected with absolute accuracy while the pump isin operation.

The open top of the casing'places the adjusting mechanism where it is inplain view and accessible for moving the shaft to adjust the impellersin their cases during the running of the pump and thus to perfectlyregulate the fiow of water through the outlet of the casing, or to shuton the flow.

The adjusting mechanism for the line shaft and impellers is capable oiindicating the position of the impellers in the cases through the opentop of the casing and the adjusting mechanism is only capable of movingthe impeller the set space allowed in said impeller cases.
